This has been changed for 1.6.1, but I recommend using prop for dynamically changing the checked property. The checked attribute is technically only meant to store the default or initial value, which is why 1.6 behaves the way it does. We understand this caused confusion which is why jQuery in 1.6.1 will behave as it did previously, but prop is still recommended if for no other reason than it will be faster.
